如何创建此软件包的安装文件？

问题描述 投票：0回答：1

我正在开发 CSXCAD python 模块。当前安装它的过程是运行：

python setup.py build_ext -I ~/opt/openEMS/include -L ~/opt/openEMS/lib -R ~/opt/openEMS/lib
python setup.py install

我想创建 

pyproject.toml
以及其他需要的东西，以便能够简单地使用 
pip install .
安装它。我创建了以下文件：

pyproject.toml

[build-system]
requires = ["setuptools","cython","numpy"]
build-backend = "setuptools.build_meta"

[tool.setuptools]
py-modules = ["CSXCAD"]

[project]
name = "CSXCAD"
version = "0.0.1"
authors = [
  { name="Example Author", email="[email protected]" },
]
description = "A small example package"
readme = "README.md"
requires-python = ">=3.8"
classifiers = [
    "Programming Language :: Python :: 3",
    "License :: OSI Approved :: MIT License",
    "Operating System :: OS Independent",
]

[tool.setuptools.cmdclass]
build_py = "_custom_build.build_py"


_custom_build.py

from setuptools import Extension
from setuptools.command.build_py import build_py as _build_py
from pathlib import Path

class build_py(_build_py):
    def run(self):
        self.run_command("build_ext")
        return super().run()

    def initialize_options(self):
        super().initialize_options()
        if self.distribution.ext_modules == None:
            self.distribution.ext_modules = []

        self.distribution.ext_modules.append(
            Extension(
                "*", 
                [Path(__file__).parent/"CSXCAD/*.pyx"],
                language = "c++",
                libraries = ['CSXCAD'],
            ),
        )

它失败了：

$ pip install .

  ERROR: Failed building wheel for CSXCAD

我猜这是因为 

-I ~/opt/openEMS/include -L ~/opt/openEMS/lib -R ~/opt/openEMS/lib
选项没有被使用，但我不知道把它们放在哪里。

看起来编译器找不到必要的头文件，特别是“CSXCAD/ParameterObjects.h” 尝试像这样更新 your_custom_build.py 

import os
from setuptools import Extension
from setuptools.command.build_py import build_py as _build_py
from pathlib import Path

class build_py(_build_py):
  def run(self):
      self.run_command("build_ext")
      return super().run()

  def initialize_options(self):
      super().initialize_options()
      if self.distribution.ext_modules == None:
          self.distribution.ext_modules = []

      openems_path = os.environ.get('OPENEMS_PATH', '~/opt/openEMS')
      openems_path = os.path.expanduser(openems_path)

      self.distribution.ext_modules.append(
          Extension(
              "*", 
              [Path(__file__).parent/"CSXCAD/*.pyx"],
              language="c++",
              libraries=['CSXCAD'],
              include_dirs=[f"{openems_path}/include"],
              library_dirs=[f"{openems_path}/lib"],
              runtime_library_dirs=[f"{openems_path}/lib"],
              extra_compile_args=['-std=c++11'],  # Add this if you need C++11 features
          ),
      )

并更新 pyproject.toml 文件以包含一些构建要求：

[build-system]
requires = ["setuptools", "cython", "numpy", "wheel"]
build-backend = "setuptools.build_meta"

[tool.setuptools]
py-modules = ["CSXCAD"]

[project]
name = "CSXCAD"
version = "0.0.1"
authors = [
  { name="Example Author", email="[email protected]" },
]
description = "A small example package"
readme = "README.md"
requires-python = ">=3.8"
classifiers = [
    "Programming Language :: Python :: 3",
    "License :: OSI Approved :: MIT License",
    "Operating System :: OS Independent",
]

[tool.setuptools.cmdclass]
build_py = "_custom_build.build_py"

您可以自定义特定的构建环境。希望有帮助。
